浙北区域长兴耕地土壤质量状况分析

The Analysis of the Farming Soil Quality Conditions in the Changxing City which in the North of Zhejiang Province

通过采样调查分析探讨了浙北区域长兴耕地的土壤肥力状况,发现最近20多年长兴耕地土壤肥力质量发生了一定的变化。土壤有机质、全氮含量略有上升;土壤有效磷平均含量比20年前略增加,但缺磷状况仍十分明显;速效钾含量略有下降,仍处于较低水平,不能满足作物正常生长的需要。土壤酸化已成为土壤退化的新问题。土壤肥力质量的变化与近20年来肥料结构、种植制度改变和工业发展等有关。

Through the soil sampling diagnosis, we discuss the condition of the farming soil quality of Changxing city which in the north of Zhejiang province.And we have found that the quality of the soil fertility has changed. The content of soil ulmin,and the entire nitrogen have slightly rise; compares to 20 years ago, the average content of soil effective phosphorus has slightly increased,but the condition that the soil lack of the phosphorus is still obviously;Athough the content of fast-acting potassium has slightly down,it still stand in a low level,so the soil can＇t satisfies the needs of the plant normal live.The soil acidification became the soil degenerate new question.The change of soil fertility quality is related to the fertilizer structure,and the change of planter system ,and the change of industrial development and so on in the recent 20 years.
